engine idle
Reply #1 –
well for starters the first thing you always wanna check with a bad idle is what controls the idle--the IAC, Idle Air Control, motor, which is attached to the side of your throttle body. Thats why "it cant be set". If its really dirty/gunky inside clean it out WELL, i think you should also lube the stuff you can see through the two holes with 3 in 1 oil or something (wait for more replies not sure on that but i thought somehwere somebody mentioned oiling it)
once youre sure the IAC is functioning right, then move onto other stuff.
good luck!
